SKYLIGHT.

SPECIFICATION forming part of Letters Patent No. 228,443, dated June 8, 1880.

Application filed February 6, 1880.

To all whom it may concern:

Be it known that we, FRANK M. CAMPBELL and ANTHONY O. DUNLEVY, of St. Louis, in the county of St. Louis and State of Missouri,- have invented a certain new and Improved Skylight; and we do hereby declare that the following is a full, clear, and complete description thereof.

The nature of this invention relates to a certain improvement in skylights, by the use of which improvement dust, rain, snow, 850., are prevented from drifting in under the caps or hoods covering the edges of the sash of the skylight.

The invention alluded to is an improvement on a skylight for which apatent, No. 196,784, was granted to the aforesaid Campbell the 6th day of November, 1877. 4

A full description of the invention first referred to will be found in the following specification, reference being had to the accompanying drawings, making a part of the same, in which I Figure 1 is a top view of the skylight. Fig. 2 is a view taken looking at the eaves. Fig. 3 is an end view.

Like letters of reference refer to like parts in the several views.

For a full understanding of thenature and importance of our improvement above mentioned, a description of the skylight frame work to which our invention is applied will be necessary, and for a more detailed description of the said patent reference may be had thereto without including it entirely herein.

It is well known in the art that skylights as usually constructed admit of the drifting in of snow, rain, dust, &c., which is attended with serious inconvenience and expense; and the object of this invention is to avoid these difficulties. The improvement set forth is applicable to skylights of various construction.

The description of our invention is as follows: Each bar of the frame or sash is made of a single piece of sheet metal, as seen at A, Fig. 2, which represents an end view of the sash-bars. A portion of the casing or cornice is shown as broken away, that the ends of the bars may be seen. A perspective detached view of the same is shown in Fig. 3. In said views it will be seen that each of the bars is composed of a single piece of sheet metal so bent as to form the central upright parts or webs, B C, and the gutters D E, respectively, on the sides thereof, also forming, at the bottom of the web 0, flanges F and G, one on each side of the said web 0, which flanges F and G also serve as gutters.

The longitudinal bars A and the transverse bars A are connected to each other by adjusting the like parts of the one to the corresponding parts of the other, which are then united by soldering. WVhen the several parts are thus together all the corresponding parts are related to each otheras, for instance, the gutters and flanges of the bars arranged at I right angles therewith.

H represents the plates of glass, supported upon the edges of the gutters, and. over which the edges of the glass project, as seen in Fig. 2, that the drippin gs from the glass may fall into the gutters.

Over the edges of the plates of glass and the edge of the bars projecting above the surface of the glass are placed caps or hoods I, made fast in place by clamps J. Said clamps consist of a strip of metal doubled upon itself, the united ends of which are secured to the part B of the bar, whereas the free ends thereof project upward through the cap, and are then bent down thereon transversely, as seen in Fig. 1, thereby drawing the edges of the cap closely down upon the face of the plates of glass.

It is found in practical experience that the caves of the cap I cannot be drawn so closely down upon the glass as to prevent air, rain, snow, dust, &c., from finding their way under, especially when glass is used, leavingaroughened surface. In consequence of dust and snow making their way under the edges of the cap, the gutters D and E become more or less filled up, causing an obstruction to a free flowing of water in the gutters, and rendering them liable to overflow, thereby doing damage to the interior of the building.

In the more modern style of sash made of metallic sheets, such as our sash is made of, some manufacturers use putty with a large mass of it within the cap, which, when hardened, is Well known to cause breakage of the glass from contraction and expansion of the bars, and hence in a "cry short time the snow, dust, air, and rain will find admittance.

To avoid this difliculty is the purpose of this iiwention, which, in connection With the sash frame, consists in filling the space immediately under the cap with a packing of fibrous or floeculent material, or its equivalent, as seen at C. Said packing is stuffed in compactly over and about the end of the upright part or Web B and pressed down firmly upon the glass covered by the caps by means of the clamps J on bending them down over the caps for holding them in place.

The packing of hair, Wool, felt, or cottonwool (the former is preferable) is arranged under the caps, which effectually excludes not
